B

$$\frac{{\left( {{{\text{r}}^2} + {{\text{R}}^2}} \right)\sin \varphi }}{2}$$

C

$$\frac{{\left( {{\text{r}} + {\text{R}}} \right)\cos \varphi }}{2}$$

D

$$\frac{{\left( {{\text{r}} + {\text{R}}} \right)\sin \varphi }}{2}$$

when a truck travels at 60 miles per hour, it uses 30 percent more gasoline to travel andy distance than it does when it travels at 50 miles per hour. The truck can travel 20 miles on a gallon of gas if it is travelling at 50 miles per hour. The truck has only 10 gallons of gas and is 160 miles from its destination. It takes 20 minutes for the truck to stop for gas . How long will it take the truck to reach its final destination if it is driven at 60 miles per hour?

A

160 minutes

B

180 minutes

C

190 minutes

D

192 minutes
