Question 1100998
<br>
Mwangi starts at 7:30am and cycles at 16km/hr.  When Otieno starts cycling at 8:00am,Mwangi has cycled 8km, so now the two of them are 32km apart.<br>
Their combined cycling speed is 16+8=24 km/hr.<br>
The time it takes them together to cover 32km is 32/24 = 4/3 hours, or 1 hour 20 minutes, so they meet at 9:20am.
