Carlos and Diego are racing around the block. Carlos runs around the entire block in 3 minutes. Diego runs around half the block in 2.5 minutes and then is tripped by a dog and can't finish. Assuming he kept up the same speed the entire race, what would've been the average time in seconds for the racers?

How many minutes would it take to run around half the block? ** If he finished the race, it would've taken 5 minutes because 2.5 x 2 =

<<2.5*2=5>>5 How many minutes would it take to run around the entire block? ** Their total time would've been 8 minutes because 3 + 5 = <<3+5=8>>8 How many minutes would the average be? ** The average would've been 4 minutes because 8 / 2 = <<8/2=4>>4 How many seconds would the average be? ** The average time in seconds would've been 240 because 4 x 60 = <<4*60=240>>240 #### 240 If Ruby is 2 centimeters shorter than Pablo. Pablo is 70 centimeters taller than Charlene. Janet is 62 centimeters tall and Charlene is twice that tall. How tall is Ruby? How tall is Charlene? ** Charlene is 2 * 62 cm = <<2*62=124>>124 cm tall. How tall is Pablo? ** Pablo is 70 cm + 124 cm = <<70+124=194>>194 cm tall. How tall is Ruby? ** Ruby is 194 cm - 2 = <<194-2=192>>192 cm tall. #### 192 A party of 4 order 3 dozen oysters on the half shell for $15.00 a dozen, 2 pounds of steamed shrimp for $14.00 a pound and 2 pounds of fried clams for $13.50 a pound.
