Answer:
93
Step-by-step explanation:
Key :
A1 = Algebra 1
A2 = Algebra 2
Alright so basically lets first look at the info they gave us :
We have 5 more than twice as many students taking A1 than we do A2.
We have 44 students taking A2.
And we need to find the least amount of students that could be taking A1.
So we need to take the amount of students taking A2 (44) and double it to find the amount taking A1.
So we can do 44 x 2 = 88 to get this.
But the problem also states there is 5 more then twice the number of students taking A2.
So we have that 88 but now we just need to add 5 to make up for them telling us that in the problem.
So :
88 + 5 = 93
Our final answer and least amount of students taking A1 is 93 students.
Question:
The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London
Answer:

Step-by-step explanation:
Given



Required
Determine the time of arrival
First, we need to calculate the time to complete the journey.

Make Time the subject

Substitute values for Distance and Speed


The arrival time is:


Split


Convert 0.9 hours to minutes



Total distance 272 miles.
Total speed (when travelling toward each other) = 75+95=170 mph
Time to meet = 272/170=1.6 hours
