Answer:
Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.
Step-by-step explanation:
Given:
Total Distance = 555 mile
Total time = 5 hour
Let time taken to travel at 115 mph be t
So Time taken to travel at 105 mph will be equal to difference between Total time and time taken to travel at 115 mph.
Time taken to travel at 105 mph =
Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.
Framing in equation form we get;
Distance traveled in 115 mph =
Also;
Distance traveled in speed 105 mph will be equal to speed multiplied by time taken to travel at 105 mph.
Framing in equation form we get;
Distance traveled in 105 mph =
Now Total Distance traveled is equal sum of Distance traveled in 115 mph and Distance traveled in speed 105 mph
Time taken to travel at 115 mph = 3 hrs.
Time taken to travel at 105 mph =
Now Distance traveled in 115 mph =
Distance traveled in 105 mph =
Hence Distance traveled at speed 115 mph is <u>345 miles</u> and Distance traveled at speed 105 mph is <u>210 miles</u>.
There are 3 seats currently, and there will be 4m extra seats if he buys m tables.
So, buying m tables give a total of seats.
If we want this total to be at least 75, we have
