Question

A speedboat traveling at a constant speed arrives at its destination in 35 minutes. If it travels 70 miles, then what was the speedboat’s speed?

Answer 1

120 mph

Explanation:

Distance = rate * time

D = 70 miles

t = 35 minutes

So that gives us:

70 mi = r(35 min)

Divide both sides by 35 min:

70/35 mi/min = r

simplify:

2 mi/min = r

If you wish to convert to miles per hour, remember that there are 60 minutes in an hour:

2 * 60 = 120

120 mph = r
