Answer:
a) 3308 km/hr
b) 1055 m/s
c) 3 Mach
Explanation:
a) convert Mach 2.7 to km/hr
We need to convert Mach 2.7 to km/hr
We know that :
1 Mach = 1225 km/hr
So, multiply 2.7 with 1225 to convert 2.7 Mach into km/hr
2.7 Mach = 2.7 * 1225 km/hr
= 3307.5 km/hr
Rounding off to whole no
= 3308 km/hr
b) Mach 3.1 to meter per second
We need to convert Mach 3.1 to m/s
We know that :
1 Mach = 340.3 m/s
3.1 Mach = 3* 340.3 m/s
= 1054.93 m/s
Rounding off to whole no
= 1055 m/s
c) 3650 km/hr to Mach
We need to convert 3650 km/hr to Mach
We know that :
1 km/hr = 0.000816327 Mach
3650 km/hr = 3650 * 0.000816327 Mach
= 2.97 Mach
Rounding off to whole no
= 3 Mach
