Question

To participiate in a competition a girl driver a cycle for 3 hours and
30 minute . The speed for first half is 25/6msec and second half is 20 km hour find the total distance covered

Answer 1

Step-by-step explanation:

Total time = 3 hrs 30 minutes

First half means 1 hrs 15 minutes = 75 minutes

Second half = 1 hrs 15 minutes =75 minutes

Speed for first half = 25/6 m/sec = 250 m/minutes

Distance covered in first half = time * speed

= 75 * 250

= 18750 metre

Speed for second half =20 km/h= 20000 m/h

or. 1000/3 m/minute

Distance covered in second half = time * speed

= 75 * 1000/3

= 25000 metre

Total distance covered = 18750 m + 25000m

=43750 metres

or 43.75 km

Total distance covered by that girl = 43.75 km
