Question

A car traveling at constant speed traveled 262.5 miles in 3 1⁄2 hours. What was the car's speed?

Answer 1

Just divide 262.5 and 3 1/2.

262.5 / 3.5 = 75

So the car's speed was 75 miles per hour.

Answer 2

When at a constant speed V, you travel a distance D in a time T defined by D=V*T

Hence V=D/T=262.5/(3+1/2)=75

The car's speed is 75mph
