Answer: Answer is C.
Step-by-step explanation:
They will meet at 3:00 p.m.
Since Ryan traveled 245 miles in 3.5 hours, he traveled at a speed of 245/3.5=70 mph. Janelle traveled 260 miles in 4 hours; she traveled at a speed of 260/4=65 mph.
Together, they had traveled 245+260=505 miles by noon. This leaves 910-505=405 miles to travel.
If Ryan stays at a constant rate of 70 mph, his distance is given by 70t. If Janelle stays at a constant rate of 65 mph, her distance is given by 65t. Their distances together equal 405:
70t+65t = 405
Combining like terms,
135t = 405
Divide both sides by 135:
135t/135 = 405/135
t = 3
3 hours after noon will be 3:00 p.m.
