Motorcyclist: 2 hours

Truck: 3 hours
Bicyclist: 7.5 hours
Let the first angle be A and the second be B.
Complementary angles add up to 90° so:
A + B = 90
We are also told:
A = 6 + 3B; substituting this into the first equation:
6 + 3B + B = 90
B = 21°
A = 6 + 3(21)
A = 69°
I’m pretty sure it’s 1.99
