Answer:
4.8 hours
Step-by-step explanation:
Distance = speed × time
If Tim drove 4 hours at 60 miles per hour
Than he drove a total of 4×60 miles
He drove 240 miles
Time = distance ÷ speed
If he drove 240 miles at 50 miles per hour
Than he took 240÷50 hours
He took 4.8 hours (4 hours and 48 minutes)
Answer:
Step-by-step explanation:
40/100 musicians .75*40= 30
30 is to 100
as 38 is to x
30 38
---- = ------ Cross multiply
100 x
30x=3800
divide by three to get
126 and 2/3
you can't split people, so it would be closer to about 127 students.
Answer:
1/3 to 1/2 teaspoons of lemon extract
Step-by-step explanation:
The proportions you say are ...
1 tsp lemon extract : 2 tbsp lemon juice
extract : juice = 1 tsp : 6 tsp = 1 : 6
If you have 2-3 teaspoons of lemon juice, you have the equivalent of 2/6 to 3/6 = 1/3 to 1/2 teaspoons of lemon extract.
A1=-15
a2=a1+d→-4=-15+d→d=11
