Answer:
5 hr.
Step-by-step explanation:
this is because one car is moving at 30 miles an hour and the other at 30+20 miles an hour = 50mph. so after 1 hour one car would have gone 30 miles and the other 50 = 80 altogether not 400 yet. After 2 hours one car would have gone 60 miles and the other 100 = 160 not 400 yet. ECT... After five hours one car has gone 150 mile (30mph*5hr = 150miles) and the other 250miles (59mph*50hr = 250miles) = 400, since 150+250=400. Therefore it would take 5hr for the cars to meet. and crash ._.
<span>1. 16y = 164 <=> y = 164/16 <=> y = 10.25 or 10 + 1/4. So the answer is a. 2. 8Z = 64 <=> Z = 64/8 <=> Z = 8. So the answer is a. 3. D = ABC <=> C = D/AB. So the answer is c.</span>
What do you mean solve...There is no equation
