Answer:

yes we will reach at 10:00 a.m. and will be able to attend the meeting

Answer 2

Answer:

Time taken to travel first half distance = 100/ 50 = 2 hrs

Time taken to travel second half distance = 100/v

Average speed = 200/ (2 + 100/v)

70 = 200/ (2 + 100/v)

2 + 100/v = 20/7

100/v = 20/7 - 2 = 6/7

v = 100 * 7/6 Km/h

v = 700/6 km/h
