Answer:
1 . Total time = 1 hr 55 minutes
2 Distance = 121 km
Step-by-step explanation:
Mattew journey
stage a
Distance = 20km
Speed = 30km/h
Time = distance/speed
Time = 20/30
Time = 2/3 h
Time = 40 minutes
Stage b
Distance = 50 I'm
Speed = 100 km/h
Time = distance/speed
Time = 50/100
Time = 0.5 h
Time = 30 minutes
Stage c
Distance = 30 km
Speed = 40 km/h
Time = distance/speed
Time = 30/40
Time = 3/4 h
Time = 45 minutes.
Total time taken =( 40 + 30 + 45 ) minutes
Total time = 115 minutes
Total time = 1 hr 55 minutes
2.
Speed =60 km/h
Time= 6 minutes + x
And x = 1 hr 55 minutes
Time = 1 hr 55 minutes + 6 minutes
Time = 2 hr 1 minute
Time = 2.01666667 hr
Distance covered = speed * time
Distance = 60*2.016667
Distance = 121 km
The number of people who grow potatoes is 3 times the number that grow sugar beet.
⇒ 48 + x = 3( x + 12)
--------------------------------------------
Solve for x :
--------------------------------------------
48 + x = 3( x + 12)
48 + x = 3x + 36
2x = 12
x = 6
--------------------------------------------
People who do both grow either.
--------------------------------------------
Number of people who does not grow potato or sugar beets = 100 - 48 - 12 - 6 = 34
------------------------------------------------------------------------------
Answer: The answers are 6 and 34.
------------------------------------------------------------------------------
"6" is inbetween "48" and "12".
"34" is outside the two circles.
Answer:
She is incorrect; Paloma's ratio of seconds travelled to feet travelled is 1:10.
Step-by-step explanation:
Her ratio is 1:10 because the first number is the number of seconds, and the second number is the number of feet. So for every 1 second, she travels 10 feet, as indicated in the original problem.
Hope this helps.
