Question

Martina walked 3/4 of a mile in 1/5 of an hour. At this rate , how far can Martina walk in one hour?

Answer 1

Martina can walk 3.75 miles in one hour at her current pace, calculated by multiplying her walking speed of 3/4 mile per 1/5 hour by 1 hour.

Step-by-step explanation:

The question is about determining how far Martina can walk in one hour based on her rate of walking 3/4 of a mile in 1/5 of an hour. To find the distance Martina can walk in one hour, which is simply finding her walking speed, we set up a ratio where the distance is in the numerator and time is in the denominator.

The ratio for Martina's walking speed is:

Speed = (Distance)/(Time) = (3/4 mile)/(1/5 hour)

To find out how far Martina can walk in one hour, we will multiply this speed by 1 hour:

Distance in one hour = Speed × 1 hour

This calculation simplifies to:

Distance in one hour = (3/4 mile)/(1/5 hour) × 1 hour

Distance in one hour = (3/4 × 5/1) mile

Distance in one hour = 15/4 mile or 3.75 miles

Therefore, Martina can walk 3.75 miles in one hour at her current pace.

Answer 2

Hey there!


To make this easier, we need to transform the numbers in decimal

3/4 = 0.75

1/5 = 0.2

So Martina walks 0.75 miles in 0.2 hour. They want us to find how far will she wake in 1 hour.

So we say:

0.75......>0.2 hr
x...........1 hr

Cross multiply

0.2 * x = 1 * 0.75

0.2x = 0.75

x = 0.75/0.2

x = 3.75

Martina will work 3.75 miles in one hour.

I hope this helps!
