A speedboat racer travels at a steady rate of 0.75 of a mile per 0.25 of a minute.
How many minutes does it take for the boat to travel 3 miles?
I have 0.75 (is that correct?)
How long will it take for the boat to travel 7.5 miles?
I have 1.88 (is that correct?)
First question:
0.25 min= 1/4 min
velocity=distance/time=
0.75/(1/4)=0.75*4 [Becouse 1/(1/4)=4]
velocity=0.75*4=3 miles/min
time=1 min
Second question:
time=distance/velocity= 7.5/3= 2.5 min
