Question

Rita walked 5 upon 7 km in 1 hour how far does she go in 3 whole 1 upon 2 hours.

Answer 1

Distance travelled in 1 hour is 5/7km

we need to find distance in 3½ hours

speed = \frac{distance}{time} \\ = \frac{ \frac{5}{7} }{1} \\ speed = \frac{5}{7} kmh

distance = speed × time

5/7×7/2

\huge\bold{2.5km}

Answer 2

Answer:13.125

Step-by-step explanation:

3 3/4 means 15/4 km in 1 hour

Then for 3 hours

15/4 × 3=45/4=90/8

For 1/2 an hour

15/4 × 1/2=15/8

Therefore in 3 1/2 hours is

90/8+15/8=105/8

=13.125 km
