Question

Lenny runs a 100-m dash in 15.4 s. Gary runs a 450-meter course in 112.5 seconds. Bruford runs a 950- meter course in 237.7 seconds. Which athlete is the fastest? Round each speed to one decimal place.

Answer 1

The Answer is Lenny runs the fastest. First choose a common value (in meters) for each of them. Let's say 100m. So We already have Lenny (He runs at the rate of 15.4s) Convert the other's times into 100 m also. For Gary it is (100*112.5)/450 which is 25 and Buford runs at 25.02 s (100*237.7)/950 Hence Lenny is the fasterst
