Question

At what rate is a car traveling, if it goes 157.5 miles in 2.5 hours?

Answer 1

Answer:

Rate basically means 'change with time'.

So here rate means velocity, as velocity is changing of distance with time.

hence,

$v = \frac{distance}{time} = \frac{157.5 \: mile}{2.5 \: hr} = 63 \: miles \: per \: hour$
