Question

Rajesh can walk 2 ¼km in one hour.How long take him to walk to his school which is 36km?​

Answer 1

Step-by-step explanation:

x+ 7 and 3/5 = 18,

or

x + 38/5 = 18,

or

5x = 90–38 = 52,

or

x = 52/5.

So you need to add 10 and 2/5 to 7 and 3/5 to get 17+(2+3)/5 = 17+1 = 18.

Answer 2

Step-by-step explanation:

GIVEN:

v = 2 1/4 km/hr

t = ? if x = 36 km

SOLUTION:

v = d/t

vt = d

t = d/v

t = 36 km/ (2 1/4 km/hr)

>cancel the unit km

t = 16 hr ANSWER
