Well, if the truck traveled for one hour, that means the car traveled for two.
60+70+70=200
It's not that difficult to just guess and check, even if it's a bit time consuming.
Let's try three hours for the truck.
60+60+60+70+70+70+70=460
That's too much, so we'll try two hours.
60+60+70+70+70=330
The truck traveled two hours, and the car traveled three hours, since the car traveled one hour longer than the truck.
All together, the car and truck drove a total of 5 hours.

Answer: 6.40 = c
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 4^2 = c^2
25 + 16 = c^2
41 = c^2
____
_/ 41 = c
6.40 = c
Answer:
3,131,313
Step-by-step explanation:
Let X represent the number of cases with diabetes in 1973.
An increase of 396% in diabetes cases in 1973 would be;
12.4 million = 396/100 × X
12.4 million = 396X/100
Cross multiply
12.4 million × 100 = 396X
X = [(12.4 million × 100) / 396]
X = 3,131,313
Therefore, the number of diabetes cases in 1973 is 3,131,313 cases
