Question

HEEEEEEEEEEEEEEEEEEELP

Answer 1

Answer:

2 miles per hour

Step-by-step explanation:

To find her walking pace in 'miles per hour' we need to divide the distance (in miles) by the time (in hours).

Speed = Distance/ Time

The time is given in minutes , but 50 minutes = 50/60 hours

=5/6 hours

1 2/3 ÷ 5/6

=5/3 × 6/5 miles per hour

Now cut it

= 2 miles per hour

Answer 2

Answer:

2 miles per hour

Step-by-step explanation:

Speed = Distance / Time

If we measure distance in miles and time in hour, we will get the speed in miles per hour.

Distance = 1 + 2/3 miles, which expressed as an improper fraction is 5/3 miles.

Time = 50 minutes which expressed in hours will be 50/60 or 5/6 hours.

(You can also see that 10 minutes is 1/6 of an hour, hence 50 minutes is 5/6 of an hour)

Speed = Distance / Time

         = (5/3) / (5/6)

We know that dividing by "a/b" is same as multiplying by "b/a"

Hence, we have:

Speed = (5/3) * (6/5)

         = (5 * 6) / (3 * 5)

         = 30 / 15

         = 2
