Question

Anjali cycles to her school at an average speed of 10km/hr it takes her 18min to reach the school if she wants to reach her in school in 15 minutes what should be her average speed

Answer 1

Answer : 17.0

Explanation:

Average Speed Anjali Cycles = 10km

Time it takes her to reach the school = 18min

If she wants to travel to school in 15mins,

Then we will have to do the following equation --> 10 / 18 Which will be

1.8.

so the time she takes to cycles the school in 1min will be 1.8km

And, The time she takes to cycle to school in 15 mins will be 1.8 x 15 which equals to --> 17.0

Answer 2

Answer:

12km /hr

Step-by-step explanation:

speed = 10km/hr

time taken = 18 min =18/60=3/10 hr

distance = speed ×time taken

dis = 10 ×3/10

= 3km

time taken =15 min= 15/60= 1/4

speed =d/t

=3km ÷ 1/4

= 12 km/hr
