please solve this question please pplease please

Answer 1

Amit speed dhould be 15 km/h

Step-by-step explanation:

Distance to school = s × t

= 12 × 15 km = 180

So, the speed = d / t

= 180 / 12

= 15 km/h

Answer 2

Given - Time and speed

Find - Speed

Solution - The speed for new timing should be 0.25 kilometres/minutes

Firstly converting the speed to kilometres/minutes.

So, speed in kilometres/minutes = 0.2 kilometres/minutes

Now, the formula to be used for the calculation of speed -

speed1*time1 = speed2*time2

Speed1 = 0.2 kilometres/minutes

Time1 = 15 minutes

Time2 = 12 minutes

Keep the values in the formula to find the value of speed2.

Speed2 = 0.2*15/12

Speed2 = 0.25 kilometres/minutes

So, the speed for new timing should be 0.25 kilometres/minutes
