Sagot :
Answer:
36 minutes
Step-by-step explanation:
Distance , speed and time:
Speed = 60 km/hr
time = 30 mins = 30/60 = 1/2 hour
[tex]\sf \boxed{\bf Distance =speed * time}[/tex]
[tex]\sf = 60 * \dfrac{1}{2}\\\\ = 30 \ Km[/tex]
Distance = 30 km and speed = 50 km/hr
[tex]\sf \boxed{\bf Time =\dfrac{Distance}{speed}}[/tex]
[tex]\sf = \dfrac{30}{50}\\\\=\dfrac{3}{5} \ hour\\\\=\dfrac{3}{5}*60\\\\= 3*12\\\\= 36 \ minutes[/tex]
Answer:
0.6 hours
Step-by-step explanation:
• First calculate the distance travelled at 60km/h:
distance = speed x time
= 60 x 0.5
= 30 km
• Now calculate the time taken at 50 km/h:
time = distance/ speed
= 30 / 50
= 0.6 hours
= 0.6 x 60 min
= 36 minutes
