Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour? miles per hour

Time = 270 mins = 4 hr. 30 mins = 4½ hr.

distance = 63 miles

thus, speed = distance travelled / time taken

speed = 63/(4½) miles per hr

speed = 14 miles per hr.

pls mark this as brainliest.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

=240

=48
