Question 588664
The length of the road is {{{ d = 3*(1/2) }}}
{{{ d = 1.5 }}} km
He started at 6:25
6:25 + 30 min = 6:55
He waits 10 min
6:55 + 10 min = 7:05
He is back at his starting point at 7:15
7:15 - 7:05 is 10 min
So, on the tricycle he covered {{{ 1.5 }}} km
in 10 min
{{{ 1.5 = r*(10/60) }}}
{{{ r = 9 }}}|
The average speed of the tricycle is 9 km/hr
