Question

mouse scurries across your kitchen floor at 2.0 feet per second. How many miles can the mouse travel in 1.5 hours (rounded to the nearest tenth)?

Answer 1

2.0 times 60= 120 feet per minute
120 times 90= 10,800.0 feet
10,800 times 0.000189= about 2.0 miles

Answer 2

Answer: the mouse can travel a distance of 2.05 miles in 1.5 hours

Explanation:

The speed of the mouse is 2ft/s

We want to know how many miles will the mouse travel in 1.5 hours, so the first steep is change the units:

1 mile = 5280 feet

so 2 feet = (2/5280) miles

Then the speed is:

s = (2/5280) milles per second.

now, in one hour and half, we have 90 minutes, and a minute has 60 seconds, so 1.5 houes is equivalent to:

90*60s = 5400s

So the distance that the mouse moves in 1.5 hours in miles is:

D = (2/5280)*5400 miles = 2.05 miles
