Answer:
At 11:00 am the both trains will be at same distance away from Roseville
Step-by-step explanation:
The first train was 40 miles away from Roseville at 7:00 am
After some time t the both trains will be at the same distance away from Roseville.
We will make equation for that situation
d- distance v1= 40mph and v2= 50mph - velocity
d = v1*t + 40 = v2*t => v2*t - v1*t = 40 => t (v2-v1) = 40 -> t = 40/ (v2-v1)
t = 40/(50-40) = 40/10= 4h t = 4h
7:00 am * 4h = 11:00 am
Good luck!!!
Answer:
19.55 $
Step-by-step explanation:
3.45$×10=34.5=150% of his money overall
34.5÷3=11.5
11.5×2=23= 100% of his money
23-15%=19.55$
I think its saying find the mixed numbers but keep the denominator
$47.99+$2.88=$50.87 (total cost)
$60.00-$50.87=$9.13
he should get back $9.13
